PUMP.

SPECIFICATION forming part of Letters Patent No. 490,776, `dated. January 31, 1893. Application tiled July 25, 1892. Serial No. 441,171. (No model.)

To all whom. it muy concern:

Be it known that I, MORRIS D. TEMPLE, a citizen of the United States, residing at Ghicago, county of Cook, in the State of Illinois, have invented certain new and useful Improvements in Pumps, of which I dodeclare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of the speci ication.

My present invention has for its object to provide a simple, cheap and effective pump,

which shall serve not only to raise water from wells, cisterns, or like receptacles, but which shall serve also to purify the water of such receptacles by forcing a supply of air into the body of the water, thereby destroying animal'cula, organic matter or like disease germs contained therein, and so rendering and maintaining the water in a pure and wholesome condition.

Prior to my invention it has been proposed to construct pump mechanism fol-aerating the water of wells and cisterns, and I do not wish, therefore to be understood as claiming broadly a pump designed for such purpose,

my invention residing in the novel feature of construction hereinafter described, illustrated in the accompanying drawings and particularly dened in the claims at end of this specification.

vFigure l is a view in vertical section through a Well or cistern in which my improved pump is located, parts being shown in section and parts in elevation. Fig. 2 is an enlarged view in central vertical section through the submerged cylinder and adjacent parts, certain parts being shown in elevation.

`A designates a submerged cylinder attached by a water discharge pipe B, to a pump head C, which may be of any of the ordinary constructions for suction and lift pumps. The cylinder A is supplied with water through the inlet passage a, this passage being provided with a check-valve 2 of suitable construction. A suitable check-valve 3 in the top of the cyl` inder serves 'to prevent the water from running down from the discharge pipe B when downward movement is imparted to operating piston D by the piston rod cl, and pump handle d. In the base of the cylinder A is formed an air inlet passage a', leading into the cylinder below the piston, and an air outlet passage a2 through which the air supply will pass into the body of the water within the well or cistern. These passages a and a2 will be furnished with suitable check valves 4 and 5, the valve 5 serving to'prevent the passage of water into the base of the cylinder and valve 4. insuringthe passage of the-air from the cylinder into the Water as the piston is forced downward. When the cylinder A is submerged, an air inlet'pipe E will connect with the air inlet passage a', this pipe E lead- 'ing preferably to the top of the well or cistern and terminating beneath the perforated casing C provided for the pump. l From the vforegoing descri-ption it will b seen that as the piston D is operated it will upon its up stroke raise through the pipe B the water admitted by the water inlet passage above the piston and at the same time will draw air through the pipe E and the air inlet passage a into the cylinder beneath the piston; while upon the down stroke of the piston the check valve 3 will prevent the descent of the water column, the check valve 2 will open to admit water to the cylinder, the check valve 4. will close toprevent the return of air through air inlet passage a', and the check valve V5 will open to permit the escape of air from below the piston through the air outlet passage a2 into the body of water within the well or cistern. into the body of Water serves to aerate it and thus effectively destroy the bacteria and like deleterious matters and renders the water pureand potable.

In the preferred embodiment of my invention the cylinder A is formed with a cap A at its top, this cap being attached to the main The volume of air thus forced body of the cylinder by a threaded joint 6 and having a lateral extension 7 to which is connected the pipe 8, to the lower` end of whichv pipe is threaded the valve chamber 9. Preferably a transverse wall l0 formed in the cap A serves as a seat forthe check valve 3,

and the upper part of thecap A is closed by a threaded cover A2 into which is tapped the lower end of the water discharge pipe B. Preferably also the base'A3 of the cylinder is formed separate from the body thereof and is connected thereto by a threaded joint 1l. In

IOO

this base AE are formed the air inlet and outj let passages a and a2, separated by the division wall as and the base A3 has an extension a4 Whereon is seated the check valve 5 and an extension a5 into which the lower end of the air inlet valve is tapped.

The piston D is an imperforate piston of suitable construction, the supply of air being admitted through the cylinder and beneath the piston in the manner above described.

Having thus described my invention what I claim as new and desire to secure by Letters- Patent is:

l. The combination of apump cylinder having at or near one and the same end stationary air in-let and out-let passages whereby air is admitted to and discharged from said cylinder and having at or near its opposite end water in-let and out-let passages, an air in-.let

. pipe connecting the stationary air in-let pas- 2. A pump comprising a cylinder having its base formed with air inlet and outlet passages and its upper part formed with water inlet` therefrom and provided with air inlet and outlet passages, having the cap formed separate therefrom and provided with water inlet and outlet passages, an air inlet pipe E forming a continuance of vthe air inlet passage, suitable valves for controlling the several inlet and outlet passages and a piston Working between the base and cap 'of the cylinder, substantially .as described.
